ELECTRIC LIGHTING DEVICE FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 320,606, dated June 23, 1885.

Application filed January 28, 1884. (No model.)

To all whom it may concern.-

Be it known that I, LE RoY S. WHITE, of Waterbury, in the county of New Haven and State of Connecticut, have invented anew and useful Improvement in Electric Lighting Devices for Gas-Burners, of which the following is a specification.

My invention is more particularly applicable to pendent burners in which the cockplug is opened and closed by pulling down on a chain or other pendent device; but it is also applicable to burners in which the plug is intended to be turned by hand.

My invention relates to a gas burner in which is employed a straightway-cock plug capable of being turned in opposite directions to open and close, and in which an electric conductor having a fixed contact is attached to the burner, and an arm carrying a movable contact is attached to and moves with the cock'plug.

A very important object of my invention is to simplify the construction of electric lighting devices for gas-burners, and to dispense with springs, which are liable to break and get out of order; and a further object of my invention is to provide an electric lighting device for a gas-burner which will make contact only once at each opening and closing movement of the cock-plug.

The invention consists in novel combina tions of parts,hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a burner embodying my invention, the cock-plug being open. Fig. 2 is a side view showing the position of the several parts during the closing movement of the plug. Fig. 3 is a horizontal section on the line 00 at, Fig. 2. Fig. 4 is a side view showing the position of the several parts during the opening movement of the cock-plug. Fig. 5 is a sectional View of a portion of the burner with the cock-plug in its open position, and Fig. 6 is a view similar to Fig. 5, showing the cock in its closed position. v

Similar letters of reference designate corresponding parts in all the figures.

A designates the burner base, and A the tip, which is or may be of the ordinary form.

B designates the cock-plug, fitted to a suit- This arm C is insulated from the burner-base at Z), and a conductor may be attaclied to a screw, 0, upon it. The arm C consxitutes a part of the conductor.

The plug Bis provided with laterally-extending arms (1 d and an upwardly-projecting arm, d", which carries the movable contact 0*. The arm (2 may comprise a flexible or yielding portion, d, the purpose of which will be hereinafter described.

To the two arms (I d are connected pendent cords or chains e e, to the lower ends of which are attached indicators f f, which may be made in the form of little balls or acorns. The indicator f is hollow, and the cord or chain 6 passes through it.

So far as now described the operation of the burner would be as follows: Supposing the cock-plug to be in the open position shown in Fig. 5, the several parts would occupy the position shown in Fig. 1. To shut off the gas, the pendent chain or cord 6 is pulled and the plug is turned to shut off the gas, as shown in Fig. 6. pendent chain or cord 6 is pulled down, thereby turning the plug in the direction to open and causing the movable contact 0* to act on the fixed contact 0, and thus produce a spark to ignite the gas. When the gas is turned on, the two indicators ff will be near together, as shown in Fig. 1, and when the gas is turned off the said indicators will be farther apart, as shown in Fig. 2. In Fig. 2 they are not at their full distance apart, because that figure shows the position of the parts during the closing movement of the plug.

Shoulders g g, on the piece from which the arms d d are formed, in conjunction with a fixed pin, 9', limit the turning movements of the plug B.

In order to insure the action of the contacts 0 0* when the plug is turned to open, and to prevent their action when the plug is turned to close, I employ a stationary cam, h, in combination with the flexible or yielding arm at d To open the plug when shut off, the

and an overhanging projection or lip, h, on said arm. The cam h is formed on the upper end of an arm, D,which projects upward from the burner body or base A, and the said cam and lip or projection have their upright faces beveled, as best shown in Fig. 3, so that when the plug B is turned in a direction to close the lip h will pass outside the cam h, and thus deflect the arms (2 (2*, as shown in Fig. 2, and prevent the movable contact 0* from acting on the fiXed contact 0.

WVhen the plug is turned to open, the lip h will pass on the inside of the cam h, and arm (1 will be deflected inward, as shown in Fig. 4, so as to insure the proper action of the contact 0* on the fixed contact a.

I do not claim, broadly, as of my invention the combination, with a gas-burner having a straightway-cock plug capable of being turned in opposite directions to open and close, of an electric conductor having a fixed contact attached to the burner, and an arm carrying a movable contact attached to or connected with the cock-plug, so as to be actuated by the turning of the plug to open and close. Neither do I claim, broadly, the combination, with a lever whereby the cook or valve of a gasburner may be turned to open and close, of cords, chains, or analogous pendent devices attached to opposite ends of the lever and depending therefrom separately and unconnected with each other. I only desire to include in my invention the pendent devices e 6 when they have attached to them indicators 5 ff, one of which, as f, is hollow and receives through it the pendent device 6.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1; The combination, with a ga s-burner hav ing a straightway-cock plug and electric contacts, one carried by the plug and the other fixed to an electric conductor on the burner, of the arms (2 d, the pendent devices 6 e, and the indicators f f, the former, f, being made hollow and receiving the device 6 through it,

whereby the said indicators are caused to approach and recede from each other as the cock is opened and closed, substantially as and for the purpose herein described.

2. The combination, with a gasburner having a straightway-cock plug capable of movement in opposite directions to open and close, of an electric conductor provided with a fixed contact on the burner, an arm projecting from and movable with said plug and carrying a movable contact, and a stationary cam upon the burner serving to deflect said arm outward in turning the plug to close, substantially as and for the purpose herein described.

3. The combination, with a gas-burner having a straightway-cock plug capable of movement in opposite directions to open and close, of an electric conductor provided with a fixed contact on the burner, an elastic or yielding arm projecting from and moving with said plug and carrying a movable contact, a lip or projection, h, on said arm, and a stationary cam on the burner serving to act upon said lip or-projection to deflect said arm inward as the plug is turned to open, substantially as and for the purposeherein described.

4. The combination, with a gas-burner having a straightway-cock plug capable of movement in opposite directions to open and close, of an electric conductor provided with a fixed contact on the burner, an elastic or yielding arm projecting from and moving with said plug and carrying a movable contact, a lip or projection, h, on said arm, and a stationary cam, h, on the burner serving to act upon said lip or projection to deflect said arm inward as the plug is turned to open, and outward as the plug is turned to close, substantially as and for the purpose herein described.
